CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY

The present application is related to and claims benefit under 35 U.S.C. §119(a) to Korean Application Serial No. 10-2015-0070454, which was filed in the Korean Intellectual Property Office on May 20, 2015, the entire content of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an electronic device for displaying a screen and a method of controlling the same.

BACKGROUND

Electronic devices may be wearable by a user and may be known as wearable devices. The wearable devices may include a head mounted electronic device such as a Head Mounted Display (HMD).

The HMD device may be worn on a user's body part (for example, the user's head) and provide a virtual reality environment to the user. The virtual reality environment may be provided, for example, by displaying a screen and/or various user interfaces which can implement the virtual reality.

An HMD may sense an acceleration or an angular acceleration and display a screen in accordance with the sensed acceleration or angle acceleration. Accordingly, the HMD may change and display the screen in accordance with a user's motion, and the user may experience actual reality by viewing the changed screen. Meanwhile, the user may board a transportation means while wearing the HMD. In this case, the transportation means may accelerate. For example, when the user takes a subway, the subway may accelerate at a departure time point or an arrival time point. The acceleration of the transportation means may result in an inertial force applied to the HMD included in an inertial frame of the transportation means. The HMD may sense the inertial force and change the screen in accordance with the inertial force. Accordingly, the HMD may display a screen which the user does not want.

SUMMARY

To address the above-discussed deficiencies, it is an object to provide, for use in an electronic device for correcting an inertial force and a method of controlling the same.

In accordance with an aspect of the present disclosure, a method of controlling an electronic device is provided. The method includes: an operation of acquiring motion information of an electronic device; an operation of performing an inertial force correction for removing a part by an inertial force from the acquired motion information; and an operation of displaying a screen corresponding to the inertial force-corrected motion information.

In accordance with another aspect of the present disclosure, an electronic device is provided. The electronic device includes: a display; a processor electrically connected to the display; a memory electrically connected to the processor; and a motion information sensing module that is electrically connected to the processor and acquires motion information of the electronic device, wherein the memory stores instructions to instruct the processor to perform an inertial force correction for removing a part by an inertial force from the acquired motion information and to control the display to display a screen corresponding to the inertial force-corrected motion information when the instructions are executed.

Embodiments of the present disclosure may provide an electronic device for correcting an inertial force and a method of controlling the same. Accordingly, when a user wears the electronic devices and boards a transportation means that accelerates, the electronic device may display a screen corresponding to a motion intended by the user. Therefore, it is possible to solve the problem in which the user views an unintended screen due to the inertial force.

DETAILED DESCRIPTION

FIGS. 1 through 23, discussed below, and the embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged electronic device. Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.

As used herein, the expression “have”, “may have”, “include”, or “may include” refers to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and does not exclude one or more additional features.

In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.

The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposed between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no elements (e.g., third element) interposed between them.

The expression “configured to” used in the present disclosure may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

The terms used herein are merely for the purpose of describing particular embodiments and are not intended to limit the scope of other embodiments. A singular expression may include a plural expression unless they are definitely different in a context. Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains. Such terms as those defined in a generally used dictionary may be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure. In some cases, even the term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.

The electronic device 101 may include a display. The electronic device 101 may store a virtual reality application. The virtual reality application may be an application which can provide a display similar to an actual reality to the user. According to an embodiment, the virtual reality application may display a left eye image and a right eye image corresponding to each of the user's eyes based on a stereo scheme.

The electronic device 102 may be a head mounted theater (HMT) device. The HMT device may be mounted on a user's head and fixed to the user's head even though the user moves. Further, the HMT device may also fix the electronic device 101 and thus the user may view an image displayed on the electronic device 101.

The electronic device 102 according to an embodiment may include a housing 450 provided to be worn on the user's head, a blackout part 430 fixed to the housing and provided at an area corresponding to locations of the user's eyes, and at least one input button 421 provided at one area of the housing 450. The electronic device 102 may include an input pad 425 which may receive a swipe input from the user.

The user may position the user's eyes to fit closely to the blackout part 430 and, accordingly, the user may view the image by the virtual reality application provided from the electronic device 101 without any interference from external light.

The electronic device 101 may be coupled to the electronic device 102. The electronic device 101 may be connected to the electronic device 102 through a wire or wirelessly. For example, although the electronic device 101 may be connected to the electronic device 102 based on a USB, it is merely an example and it may be easily understood by those skilled in the art that there is no limitation on the connection if data transmission/reception between the two devices 101 and 102 is possible through the connection. According to another embodiment, the electronic device 101 may be simply physically coupled to the electronic device 102.

FIG. 4B illustrates the displaying operation of the electronic device according to an embodiment.

As illustrated in FIG. 4B, the electronic device 101 may display a left eye image 461 and a right eye image 462 on the display 160. The left eye image 461 may include a first object 463 and the right eye image 462 may include a second object 464. The first object 463 may correspond to a left eye 701 and the second object 464 may correspond to a right eye 702. In FIG. 4B, an interpupillary Distance (IPD) corresponding to a distance between the left eye 701 and the right eye 702 may be D. The left eye image 461 and the right eye image 462 may correspond to the user's two eyes and may be images viewed by the user while the user feels a sense of depth. According to embodiments of the present disclosure, the left eye image 461 and the right eye image 462 may be images for the virtual reality service, and may be images configured to give a three-dimensional effect to a part of the entire screen for the virtual reality service.

The electronic device 101 may display the first object 463 and the second object 464 with a predetermined distance therebetween. The user may view as if an object image 467 exists at the intersection of a straight line passing through the left eye 701 and the first object 463 and a straight line passing through the right eye 702 and the second object 464. For example, the user may view as if the object image exists at a position spaced apart from the user by Ll.

According to an embodiment, the electronic device 101 may display the first object 463 and the second object 464, which have a loop shape.

FIG. 4C illustrates a conceptual diagram of the screen viewed by the user. As illustrated in FIG. 4C, the user may view the screen including a loop-shaped image 471.

Meanwhile, although FIGS. 4A to 4C illustrate that the electronic device 101 is separated from the electronic device 102, which the user wears, it is merely an example and the electronic device 101 may be implemented to be integral with the electronic device 102.

FIG. 5A illustrates a perspective view illustrating the user wearing the HMT device.

The user may wear the housing on the head. Further, the electronic device 101 may be coupled to the electronic device 102, and the user may view an image displayed on the display of the electronic device 101.

The electronic device 101 may display a left eye image and a right eye image on respective left and right parts of the display. The left eye image may be incident to the user's left eye and the right eye image may be incident to the user's right eye. For example, the left eye image and the right eye image may be incident to the user's entire field of view through both eyes. The user may receive a virtual reality service by viewing the images incident to both eyes.

The virtual reality application executed by the electronic device 101 may display a binocular image on the display. The virtual reality application may change and display the binocular image according to a motion (yaw, pitch, or roll) of the user or the electronic device 102.

The electronic device 102 may receive a command from the user by at least one of the input button 421 and/or the input pad 425. For example, the electronic device 101 may acquire a focus control command or a manipulation command from the electronic device 102. According to another embodiment, the user may directly input the focus control command or the manipulation command into the electronic device 101.

For example, when the user inputs a swipe gesture in a first direction of the input pad 425, the electronic device 101 may execute a control command corresponding to the swipe gesture.

FIGS. 5B to 5E illustrate conceptual diagrams illustrating screen switching of the electronic device according to embodiments of the present disclosure.

As illustrated in FIG. 5B, the user may look in a first direction 511 in a state where the user wears the electronic device 101. The electronic device 101 may display a left eye image and a right eye image for a first virtual screen 521 to allow the user to view the first virtual screen 521. The first virtual screen 521 may be a screen corresponding to a part of the entire screen configured in the virtual reality service. Meanwhile, the user may turn the user's head in a right direction 501, and the electronic device 101 may sense the rotation in the right direction 501. As illustrated in FIGS. 5C to 5E, the user may turn the user's head in a second direction 512, a third direction 513, and a fourth direction 514 from the first direction 511. The electronic device 101 may sense the rotation 501 in the fourth direction 514 from the first direction 511. The electronic device 101 may change and display the first virtual screen 521 in response to the rotation 501. For example, the electronic device 101 may display a second virtual screen 522 in accordance with the second direction 512, a third virtual screen 523 in accordance with the third direction 513, and a fourth virtual screen 524 in accordance with the fourth direction 514. More specifically, the electronic device 101 may display the left eye image and the right eye image for displaying the virtual screens, respectively. Each of the first virtual screen 521 to the fourth virtual screen 524 may be a partial screen of the entire screen for the virtual reality service. As illustrated in FIGS. 5B to 5E, the second virtual screen 522 may be a screen for a foreground arranged relatively on the right side of the first virtual screen 521, the third virtual screen 523 may be a screen for a foreground arranged relatively on the right side of the second virtual screen 522, and the fourth virtual screen 524 may be a screen for a foreground arranged relatively on the right side of the third virtual screen 523. Accordingly, as the user turns the user's head in a right direction, the user may sequentially view the foregrounds arranged relatively on the right side.

FIGS. 6A to 6C illustrate conceptual diagrams illustrating an operation of the electronic device according to embodiments of the present disclosure.

As illustrated in FIG. 6A, a user 601 may board a transportation means such as a car while wearing the electronic device 101. In this case, the transportation means may accelerate in a first direction. For example, it is assumed that the transportation means accelerates with an acceleration 611 with a vector having coordinates (a1, b1, c1). (a1, b1, c1) may be coordinates based on a predetermined point of a non-inertial frame for the transportation means, and the components may indicate sizes and directions of the x, y, and z axis components of the acceleration, respectively. For example, each of a1, b1, and c1 may have a positive value or a negative value. Meanwhile, the electronic device 101 may be included in an inertial frame corresponding to the transportation means and, accordingly, an inertial force 612 may be applied to the electronic device 101. The inertial force 612 may be applied in a direction opposite to the first direction. Meanwhile, an inertial acceleration of the inertial force 612 may have the same absolute value as that of the acceleration of the transportation means. That is, the inertial acceleration of the inertial force 612 may have a vector value of (−a1, −b1, −c1). Meanwhile, although FIG. 6A illustrates that the linear inertial acceleration is applied to the electronic device 101, it is merely an example and a rotational inertia angular acceleration may be applied to the electronic device 101.

As illustrated in FIG. 6B, the electronic device 101 may display a partial image 621 of a total image 620 such as a panorama on the display. For example, as illustrated in FIG. 6C, the electronic device 101 may display a left eye image 631 corresponding to a first image 621, which is a partial image, on a left half side of the display and display a right eye image 632 corresponding to the partial image 621 on a right half side of the display.

It is assumed that the user is viewing the first image 621 without any movement. Since the user is not moving while wearing the electronic device 101, the electronic device 101 should maintain displaying of the left eye image 631 and the right eye image 632 corresponding to the first image 621. However, as described above, the electronic device 101 may receive the inertial force 612 in the direction opposite to the first direction. The motion information sensing module of the electronic device 101 may sense the inertial force 612 as a motion of the electronic device 101 by the user. That is, the electronic device 101 may change the displayed images 631 and 632 in accordance with the inertial force 612. The electronic device 101 may determine a second image 622 to be changed in the total image 620 by the inertial force 612. The electronic device 101 may determine the second image 622 based on the direction and size of the inertial force 612. The electronic device 101 may display a left eye image 641 and a right eye image 642 corresponding to the second image 622. Accordingly, even though the user 601 desires to view the first image 621, the user views the second image 622 due to the inertial force 612.

FIG. 7 illustrate a flowchart illustrating a control method of the electronic device according to embodiments of the present disclosure.

In operation 710, the electronic device 101 may acquire motion information of the electronic device 101. The electronic device 101 may include sensors such as a linear acceleration sensor, a gyro sensor, and/or a geomagnetic sensor, which may sense various linear accelerations, rotation angle accelerations, and/or orientation information of the electronic device. The electronic device 101 may acquire motion information of the electronic device 101 based on output values from the various sensors. For example, the electronic device 101 may acquire a linear acceleration of the electronic device 101 based on the output value from the linear acceleration sensor. The electronic device 101 may acquire a rotation angle acceleration of the electronic device 101 based on the output value from the gyro sensor. The electronic device 101 may acquire a motion in orientation information on the electronic device 101 based on the output value from each of the gyro sensor and the geomagnetic sensor.

In operation 720, the electronic device 101 may perform an inertial force correction on the acquired motion information. The electronic device 101 may remove the inertial force component from the acquired motion information and, accordingly, acquire the inertial force-corrected motion information. According to an embodiment, the electronic device 101 may acquire the inertial force information and perform the inertial force correction. According to an embodiment, the electronic device 101 may receive inertial force information from another electronic device including the sensor and perform the inertial force correction by using the received inertial force information. According to an embodiment, the electronic device 101 may generate an inverse vector in accordance with the acquired inertial force information and acquire the inertial force-corrected motion information by adding the inverse vector and the acquired motion information. According to an embodiment, the electronic device 101 may measure a biometric signal and perform the inertial force correction by using the measured biometric signal. According to an embodiment, the electronic device 101 may determine whether an absolute value of the motion information is included in a preset range and perform the inertial force correction according to a result of the determination. According to an embodiment, the electronic device 101 may perform the inertial force correction by removing a linear component of the motion information. According to an embodiment, the electronic device 101 may photograph an external environment and perform the inertial force correction by using the photographed image. According to an embodiment, the electronic device 101 may perform the inertial force correction based on whether orientation information of the electronic device 101 is changed. The inertial force correction according to the embodiments will be described below in more detail.

In operation 730, the electronic device 101 may display a virtual reality screen by using the inertial force-corrected motion information. That is, the electronic device 101 may display the virtual reality screen by using motion information acquired from the user's intention. Accordingly, the user may view the intended virtual reality screen while the transportation means in which the user has boarded accelerates.

Meanwhile, the other electronic device may be included in, for example, an airplane. In this case, the other electronic device may transmit information such as an acceleration, altitude, and/or terrestrial magnetism to the electronic device 101. The electronic device 101 may perform the correction based on the received information such as the acceleration, altitude, and/or terrestrial magnetism.

FIGS. 8A to 8C illustrate conceptual diagrams illustrating an operation of the electronic device according to embodiments of the present disclosure.

In FIG. 8A, it is assumed that the user 601 boards the transportation means like in FIG. 6A. Further, the electronic device 101 may receive the inertial force 612 like in FIG. 6A. As illustrated in FIG. 6A, the inertial acceleration corresponding to the inertial force 612 may have the vector value of (−a1, −b1, −c1). Meanwhile, the user may turn the user's head to the right while wearing the electronic device 101. Accordingly, the electronic device 101 may sense a motion 810 of the electronic device 101 and acquire motion information. Here, it is assumed that an acceleration corresponding to the motion 810 is (a2, b2, c2). Accordingly, the acceleration corresponding to the motion information of the electronic device 101, which the electronic device 101 acquires, may be (a2-a1, b2-b1, c2-c1) generated by adding the inertial acceleration (−a1, −b1, −c1) and the acceleration (a2, b2, c2) corresponding to the motion 810. (a2-a1, b2-b1, c2-c1) is named an added acceleration 811. For example, the added acceleration 811 may be the left side from the user.

The electronic device 101 may display a left eye image and a right eye image corresponding to a first image 811. Meanwhile, the electronic device 101 may display a left eye image and a right eye image corresponding to a second image 812 in accordance with the added acceleration 811. Accordingly, even though the user turns the user's head relatively to the right, the user views the second image 812 arranged relatively on the left side of the first image 811.

The electronic device 101 according to embodiments of the present disclosure may ignore the inertial acceleration corresponding to the inertial force 612 and adopt the acceleration corresponding to a motion 810 actually intended by the user as motion information. The electronic device 101 may acquire inertial force-corrected motion information by performing the inertial force correction through the various methods and, accordingly, display a third image 813 corresponding to the motion 810. For example, as illustrated in FIG. 8C, the electronic device 101 may change a left eye image 821 and a right eye image 822 corresponding to the first image 811 and display a left eye image 831 and a right eye image 832 corresponding to the third image 813.

In the above description, the electronic device 101 may perform the inertial force correction on the sensed motion information and display the screen based on the inertial force-corrected motion information. Hereinafter, various inertial force correction methods performed by the electronic device 101 will be described in more detail.

FIG. 9 illustrate a flowchart illustrating an inertial force correction method according to embodiments of the present disclosure.

In operation 910, the electronic device 101 may sense motion information. The electronic device 101 may include sensors such as a linear acceleration sensor, a gyro sensor, and a geomagnetic sensor, which may sense various linear accelerations, rotation angle accelerations, or orientation information of the electronic device. The electronic device 101 may acquire motion information of the electronic device 101 based on output values from the various sensors.

In operation 920, a sensor 900 may sense an inertial force. The sensor 900 may be physically separated from the electronic device 101 and may be included in an inertial frame corresponding to a transportation means. The sensor 900 may be independent from an operation for moving the electronic device 101 by the user. For example, when the user performs an operation of rotating the head while wearing the electronic device 101, a location of the sensor 900 is not influenced by the operation by the user. The sensor 900 may sense the inertial force by the acceleration of the transportation means. The sensor 900 may include sensors such as a linear acceleration sensor, a gyro sensor, and/or a geomagnetic sensor which may sense various linear accelerations, rotation angle accelerations, and/or orientation information of the electronic device. The sensor 900 may sense the inertial force based on output values from the various sensors.

In operation 930, the sensor 900 may transmit the sensed inertial force information to the electronic device 101. The sensor 900 may transmit the sensed inertial force information to the electronic device 101 through wired or wireless communication.

In operation 940, the electronic device 101 may correct the sensed motion information by using the received inertial force information. The electronic device 101 may perform the inertial force correction by removing the inertial force component from the sensed motion information. The electronic device 101 may perform the inertial force correction by adding an inverse vector of the inertial force information and the sensed motion information. For example, in embodiments of the FIGS. 8A and 8B, accelerations corresponding to the sensed motion information may be (a2-a1, b2-b1, c2-c1). Further, the sensor 900 may sense the inertial acceleration of (−a1, −b1, −c1). The electronic device 101 may receive the inertial acceleration of (−a1, −b1, −c1) from the sensor 900. The electronic device 101 may acquire the acceleration of (a2, b2, c2) of the corrected motion information by adding the inverse vector (a1, b1, c1) of the inertial acceleration and the acceleration (a2-a1, b2-b1, c2-c1) corresponding to the sensed motion information.

In operation 950, the electronic device 101 may display a virtual reality screen by using the corrected motion information. Accordingly, as illustrated in FIG. 8C, the electronic device 101 may display the left eye image 831 and the right eye image 832 corresponding to the acceleration (a2, b2, c2) of the corrected motion information.

FIG. 10 illustrate a conceptual diagram illustrating the electronic device and another electronic device according to embodiments of the present disclosure.

As illustrated in FIG. 10, the user may board a transportation means while wearing the electronic device 101. Further, the user may wear another electronic device 1030 on the user's wrist. Although the other electronic device 1030 is illustrated as a wristwatch-type wearable electronic device, the other electronic device 1030 is not limited to the wristwatch-type wearable electronic device if the other electronic device 1030 is a device which is physically separated from the electronic device 101 and who's location is not influenced by a user's motion 1010. The user, the electronic device 101, and the other electronic device 1030 may be included in the same inertial frame.

Meanwhile, the transportation means may accelerate and, accordingly, the inertial force may be applied to all objects within the transportation means, that is, the user, the electronic device 101, and the other electronic device 1030. For example, a first inertial force 1020 may be applied to the electronic device 101 and a second inertial force 1040 may be applied to the other electronic device 1030. The first inertial force 1020 and the second inertial force 1040 may be proportional to masses of the electronic device 101 and the other electronic device 1030, respectively. The inertial acceleration corresponding to the first inertial force 1020 and the acceleration force corresponding to the second inertial force 1030 may be the same.

The user may rotate the user's head in a first direction as indicated by reference numeral 1010. Accordingly, the electronic device 101 may sense a result of a sum of motion information corresponding to the rotation 1010 in the first direction and motion information corresponding to the first inertial force 1020. A location of the other electronic device 1030 is not influenced by the user's motion, that is, the rotation 1010. Accordingly, the other electronic device 1030 may sense the second inertial force 1040. The other electronic device 1030 may transmit information on the second inertial force 1040 to the electronic device 101 as indicated by reference numeral 1050. The information on the second inertial force 1040 may be the inertial acceleration or an inverse vector of the inertial acceleration. The electronic device 101 may acquire inertial force-corrected motion information by adding the inverse vector of the inertial acceleration and the acceleration of the sensed motion information.

Meanwhile, the other electronic device 1030 may be implemented in the form fixed to the transportation means as well as that separately worn by the user in the embodiment. For example, the user may fix the other electronic device 1030 to the inertial frame of the transportation means. Alternatively, the other electronic device 1030 may be included in the transportation means. For example, the transportation means may include a sensor that may sense motion information of the transportation means and a communication module that may transmit the sensed motion information of the transportation means. In this case, the electronic device 101 may receive the motion information of the transportation means from the transportation means and perform a inertial force correction by using the motion information. When the electronic device 101 receives the motion information of the transportation means, the electronic device 101 may acquire the inertial force-corrected motion information by adding the acceleration corresponding to the motion information of the transportation means and the acceleration corresponding to the sensed motion information of the electronic device 101 without using the inverse vector. This results from the fact that the motion information of the transportation means and the inertial force have completely opposite directions.

FIGS. 11A and 11B illustrate flowcharts illustrating a control method of the electronic device according to embodiments of the present disclosure.

In operation 1110, the electronic device 101 may sense an acceleration of the electronic device 101. In operation 1120, another electronic device may sense an inertial acceleration. In operation 1130, the other electronic device may transmit the sensed inertial acceleration to the electronic device 101. In operation 1140, the electronic device 101 may generate a corrected vector by adding the sensed acceleration and an inverse vector of the received inertial acceleration. The corrected vector may be an acceleration that corresponds to a user's motion. In operation 1150, the electronic device 101 may display a virtual reality screen by using the corrected vector.

Meanwhile, on contrary to FIG. 11A, the other electronic device may transmit the inverse vector of the sensed inertial acceleration in an embodiment of FIG. 11B. That is, the other electronic device may generate and transmit the inverse vector of the inertial acceleration. The other electronic device may transmit the inverse vector of the inertial acceleration in operation 1131, and the electronic device 101 may generate the corrected vector by adding the sensed acceleration and the received inverse vector in operation 1141.

FIG. 12 illustrate a flowchart illustrating a control method of the electronic device according to embodiments of the present disclosure. The embodiment of FIG. 12 will be described in more detail with reference to FIGS. 13A and 13B. FIGS. 13A and 13B illustrate conceptual diagrams illustrating an inertial correction using a biometric signal according to embodiments of the present disclosure.

In operation 1210, the electronic device 101 may sense motion information of the electronic device. As described above, the electronic device 101 may include sensors such as a linear acceleration sensor, a gyro sensor, and a geomagnetic sensor, which may sense various linear accelerations, rotation angle accelerations, or orientation information of the electronic device. The electronic device 101 may acquire motion information of the electronic device 101 based on output values from the various sensors.

In operation 1220, the electronic device 101 may sense a biometric signal. According to an embodiment, the electronic device 101 may sense an electromyograph (EMG) signal. The EMG signal relates to electrical activity of a user's muscle and indicates electrical activity through a contraction or relaxation of the muscle. Since the muscle is under the control of a nerve and minute electric currents always flow in the muscle, information on the contraction or relaxation of the muscle may be analyzed by identifying the electric currents through electrodes. Meanwhile, it may be easily understood by those skilled in the art that there is no limitation in the type of signal if the signal can indicate a muscle movement state as well as the EMG signal.

In operation 1230, the electronic device 101 may determine whether the sensed motion information of the electronic device 101 is intended by the user based on the biometric signal. In operation 1240, the electronic device 101 may display a virtual reality screen by using a result of the determination.

For example, the electronic device 101 may determine motion information acquired while the biometric signal is not acquired as motion information by the inertial force. As illustrated in FIG. 13A, the electronic device 101 may receive the inertial force 612. Further, it is assumed that the electronic device 101 displays a left eye image and a right eye image corresponding to the first image 811. A sensor 1300 which may sense a biometric signal may be arranged near a user's neck, for example, attached to a strap. Accordingly, when the user turns the user's head, the sensor 1300 may sense a change in the biometric signal generated due to the contraction and relaxation of muscles. For example, when the user does not turn the user's head as illustrated in FIG. 13A, the sensor 1300 may not sense the biometric signal corresponding to the muscle movement. The electronic device 101 may sense motion information of the electronic device 101 including the inertial force 612 but determine that the motion information does not correspond to a motion intended by the user. That is, the electronic device 101 may not process the motion information acquired when the biometric signal is not sensed. The sensor 1300 may be included in an HMT device into which the electronic device may be inserted and, in this case, the electronic device 101 may receive information on the biometric signal from the HMT device through a wire or wirelessly.

Meanwhile, as illustrated in FIG. 13B, the user may turn the user's head to the right. In this case, the sensor 1300 may sense a biometric signal corresponding to the muscle movement. The electronic device 101 may determine motion information 810 acquired when the biometric signal is sensed as motion information intended by the user. Accordingly, the electronic device 101 may change the virtual reality screen from the first image 811 to the third image 813 in accordance with the motion information 810 and display a left eye image and a right eye image corresponding to the third image 813.

That is, the electronic device 101 may remove the motion information acquired while the biometric signal is not acquired as a part by the inertial force.

As described above, the electronic device 101 may perform the inertial force correction by using biometric information from the user.

FIG. 14 illustrate a flowchart illustrating a control method of the electronic device according to embodiments of the present disclosure.

In operation 1410, the electronic device 101 may sense motion information of the electronic device 101.

In operation 1420, the electronic device 101 may determine a range of the sensed motion information. For example, the electronic device 101 may preset the ranges shown in Table

TABLE 1 Electronic device state Acceleration range Inertial acceleration a to b Acceleration by user c to d

The inertial acceleration by the acceleration of the transportation means may be included in, for example, the range from a to b. The acceleration by the user may be generated when the user turns the user's head in order to change the virtual reality screen and may be included in the range from c to d.

In operation 1430, the electronic device 101 may determine whether the sensed motion information of the electronic device is intended by the user according to the range of the sensed motion information. For example, the electronic device 101 may identify that an absolute value of the acceleration of the sensed motion is e. When e is included in the range from a to b, the electronic device 101 may determine that the sensed motion is the inertial force by the transportation means. Further, when e is included in the range from c to d, the electronic device 101 may determine that the sensed motion is intended by the user.

In operation 1440, the electronic device 101 may display the virtual reality screen by using a result of the determination.

As described above, the electronic device 101 may perform the inertial force correction by removing the inertial force component which corresponds to motion information, outside the preset ranges.

FIG. 15 illustrates a flowchart illustrating a control method of the electronic device according to embodiments of the present disclosure. The embodiment of FIG. 15 will be described in more detail with reference to FIGS. 16A to 16C. FIGS. 16A to 16C illustrate conceptual diagrams illustrating a change in an orientation of the electronic device 101 according to embodiments of the present disclosure.

In operation 1510, the electronic device 101 may sense motion information of the electronic device. The electronic device 101 may include sensors such as a linear acceleration sensor, a gyro sensor, and/or a geomagnetic sensor, which may sense various linear accelerations, rotation angle accelerations, and/or orientation information of the electronic device. The electronic device 101 may acquire motion information of the electronic device 101 based on output values from the various sensors. For example, the electronic device 101 may acquire a linear acceleration of the electronic device 101 based on the output value from the linear acceleration sensor. The electronic device 101 may acquire a rotation angle acceleration of the electronic device 101 based on the output value from the gyro sensor. The electronic device 101 may acquire a motion in orientation information on the electronic device 101 based on the output value from each of the gyro sensor and the geomagnetic sensor. The orientation information may include a tilt information with respect to at least one axis that passes through a reference point of the electronic device 101.

In operation 1520, the electronic device 101 may determine whether the orientation of the electronic device 101 is changed. The electronic device 101 may determine whether the orientation of the electronic device 101 is changed by determining whether there is a time sequential change in the tilt information with respect to at least one axis that passes through the reference point of the electronic device 101.

When it is determined that the orientation of the electronic device 101 is changed, the electronic device 101 may determine that the sensed motion information of the electronic device is intended by the user in operation 1530. For example, when the user turns the user's head while wearing the electronic device 101 as illustrated in FIGS. 16A and 16B, a tilt degree of the electronic device 101 may be changed by θ. FIG. 16B illustrates a plan view illustrating the electronic device 101 as viewed from above, and it may be noted that a tilt degree of the electronic device 101 is changed by θ in FIG. 16B. That is, the orientation of the electronic device 101 may be changed by a user's motion.

When it is determined that the orientation of the electronic device 101 is not changed, the electronic device 101 may determine that the sensed motion information of the electronic device 101 is by the inertial force in operation 1540. For example, when an inertial force 1610 is applied in a state where the user wears the electronic device 101 as illustrated in FIG. 16C, the orientation of the electronic device 101 is not changed. Accordingly, the electronic device 101 may determine that the sensed motion information without the change in the orientation information is by the inertial force 1610.

In operation 1550, the electronic device 101 may display the virtual reality screen by using a result of the determination. For example, when it is determined that the orientation of the electronic device 101 is changed, the electronic device 101 may determine that the sensed motion information of the electronic device is intended by the user, and change and display the virtual reality screen in accordance with the motion information. When it is determined that the orientation of the electronic device 101 is not changed, the electronic device 101 may determine that the sensed motion information of the electronic device 101 is by the inertial force and maintain the virtual reality screen without any change.

As described above, the electronic device 101 may perform an inertial force correction for removing the inertial force component which corresponds to the motion information acquired while the orientation information is not changed.

FIG. 17 illustrates a flowchart illustrating a control method of the electronic device according to embodiments of the present disclosure.

In operation 1710, the electronic device 101 may sense motion information of the electronic device. The electronic device 101 may include sensors such as a linear acceleration sensor, a gyro sensor, and/or a geomagnetic sensor, which may sense various linear accelerations, rotation angle accelerations, and/or orientation information of the electronic device. The electronic device 101 may acquire motion information of the electronic device 101 based on output values from the various sensors.

In operation 1720, the electronic device 101 may determine whether the sensed motion is a rotation. For example, the electronic device 101 may sense a linear acceleration and a rotation angle acceleration and may determine whether the acquired motion information is the rotation by using the sensed data.

When it is determined that the sensed motion is the rotation, the electronic device 101 may determine that the sensed motion information of the electronic device is intended by the user in operation 1730. As illustrated in FIG. 16A, the user wearing the electronic device 101 may turn the user's head in order to view another virtual screen.

When it is determined that the sensed motion is not the rotation, the electronic device 101 may determine that the sensed motion information of the electronic device is by the inertial force in operation 1740. For example, when the electronic device 101 senses only the linear acceleration as illustrated in FIG. 16C, the electronic device 101 may determine that the sensed motion information is by the inertial force.

In operation 1750, the electronic device 101 may display the virtual reality screen by using a result of the determination. For example, when it is determined that the sensed motion is the rotation, the electronic device 101 may determine that the sensed motion information of the electronic device is intended by the user, and change and display the virtual reality screen in accordance with the motion information. When it is determined that the sensed motion of the electronic device 101 is not the rotation, the electronic device 101 may determine that the sensed motion information of the electronic device 101 is by the inertial force and maintain the virtual reality screen without any change.

As described above, the electronic device 101 may perform the inertial force correction for removing the inertial force component which corresponds to a linear component of the motion information. Particularly, when the user boards an airplane which mainly performs linear acceleration, the accuracy of the inertial force correction may be further improved.

The electronic device 101 may acquire motion information of the electronic device 101 based on output values from the various sensors.

In operation 1820, the electronic device 101 may acquire an image by photographing an external environment of the electronic device 101. The electronic device 101 may acquire a plurality of image frames over time. The electronic device 101 may include a camera module that captures the plurality of image frames of an external environment. Alternatively, the electronic device 101 may not include the camera module and, in this case, may receive a plurality of image frames from another electronic device including the camera module.

In operation 1830, the electronic device 101 may determine whether images photographed while the electronic device 101 moves are changed. The electronic device 101 may determine whether images are changed by comparing adjacent image frames in the plurality of image frames. The electronic device 101 may determine whether the images are changed based on a marker scheme or a markerless scheme.

When it is determined that the images are changed, the electronic device 101 may determine that the sensed motion information of the electronic device 101 is intended by the user in operation 1840.

When it is determined that the images are not changed, the electronic device 101 may determine that the sensed motion information of the electronic device is by the inertial force in operation 1850.

In operation 1860, the electronic device 101 may display the virtual reality screen by using a result of the determination. When it is determined that the images are changed, the electronic device 101 may determine that the sensed motion information of the electronic device 101 is intended by the user, and change and display the virtual reality screen in accordance with the motion information. When it is determined that the images are not changed, the electronic device 101 may determine that the sensed motion information of the electronic device is by the inertial force and maintain the displaying of the virtual reality screen.

For example, in FIG. 19A, the electronic device 101 may determine that the images are changed through the marker scheme. The electronic device 101 may acquire an image for a first external environment 1910 including a marker 1911 through the camera module. In this case, the inertial force 612 may be applied to the electronic device 101 but the electronic device 101 does not detect the image change. Since the electronic device 101 has not detected the image change, the electronic device 101 may maintain a left eye image and a right eye image corresponding to the first screen 811.

On the contrary to this, the electronic device 101 may acquire an image for a second external environment 1920 including a marker 1921 in FIG. 19B. The user may acquire the second external environment 1920 different from the first external environment 1910 by rotating the head as indicated by reference numeral 810. The electronic device 101 determine the image change according to the change in a location of the marker 1921 of the image for the second external environment 1920 and a location of the marker 1911 of the image for the first external environment 1910. The electronic device 101 may change the first screen 811 to the third screen 813 in accordance with the motion acquired while the images are changed and display the third image 813.

As described above, the electronic device 101 may perform the inertial force correction for removing inertial force component which corresponds to the motion information acquired while the adjacent images of the plurality of images are not changed.

FIG. 20 illustrates a flowchart illustrating a control method of the electronic device according to embodiments of the present disclosure. The embodiment of FIG. 20 will be described in more detail with reference to FIGS. 21A and 21B. FIGS. 21A and 21B illustrate conceptual diagrams illustrating an electronic device according to embodiments of the present disclosure.

In operation 2010, the electronic device 101 may acquire an image by photographing an external environment of the electronic device 101. The electronic device 101 may acquire a plurality of image frames according to the time. The electronic device 101 may include a camera module that capture the plurality of image frames of an external environment. Alternatively, the electronic device 101 may not include the camera module and, in this case, may receive a plurality of image frames from another electronic device including the camera module.

In operation 2020, the electronic device 101 may determine whether images photographed while the electronic device 101 moves are changed. The electronic device 101 may determine whether images are changed by comparing adjacent image frames in the plurality of image frames. The electronic device 101 may determine whether the images are changed based on a marker scheme or a markerless scheme.

In operation 2030, the electronic device 101 may determine motion information of the electronic device by using the changed images. In operation 2040, the electronic device 101 may display a virtual reality screen by using the determined motion information. For example, in FIG. 21A, the electronic device 101 may determine that the images are changed through the marker scheme. The electronic device 101 may acquire an image for a first external environment 1910 including a marker 1911 through the camera module. Further, the electronic device 101 may acquire the image for the second external environment 1920 including a marker 1921 in FIG. 21B. The user may acquire the second external environment 1920 different from the first external environment 1910 by rotating the head as indicated by reference numeral 810. The electronic device 101 may acquire motion information 1930 according to the change in a location of the marker 1921 of the image for the second external environment 1920 and a location of the marker 1911 for the first external environment 1910. According to embodiments of the present disclosure, the electronic device 101 may acquire three dimensional information by using a depth camera or a time of flight (TOF) camera and, accordingly, acquire three dimensional motion information. The electronic device 101 may change the first screen 811 to the third screen 813 in accordance with the motion acquired while the images are changed and display the third image 813.

As described above, the electronic device 101 may set a reference point. When using optical information, the electronic device 101 may set the reference point and ignore an acceleration and a vibration value measured when the reference point is not changed. The electronic device 101 may perform initial rendering. The electronic device 101 may first identify whether a location of the reference point is changed when there is a motion, and maintain the existing image when there is no motion. Otherwise, the electronic device 101 may perform rendering by using head tracking information when the motion is smaller than a preset threshold. When the motion is larger than the threshold, the electronic device 101 may provide the same force in an opposite direction to offset the force and display information which the user desires on the screen.

In operation 2220, the electronic device 101 may determine a relative location of the electronic device 101 with respect to the external electronic device 2200. The electronic device 101 may determine the received location of the electronic device 101 with respect to the external electronic device 2200 and, accordingly, determine the relative location.

In operation 2230, the electronic device 101 may determine motion information of the electronic device 101 according to a change in the determined relative location. For example, as illustrated in FIG. 23, the electronic device 101 may determine a first relative location 2330 of the electronic device 101 with respect to a reference 2310. The reference 2310 may be the location of the external electronic device 2200. The electronic device 101 may determine the first relative location 2330 based on, for example, displacement between one point 2320 of the electronic device 101 and the reference 2310. The electronic device 101 may determine a second relative location 2350 of the electronic device 101 with respect to the reference 2310. The electronic device 101 may determine the second relative location 2350 based on, for example, displacement between one point 2340 of the electronic device 101 and the reference 2310. The electronic device 101 may determine motion information according to a difference θ between the first relative location 2330 and the second relative location 2350.
